On the downside, Eclipse is awfully memory hungry in my experience. I've heard that before, but I can't really understand why - I haven't had memory issues with eclipse in years. I thought it might be because I've had at least 4gb of RAM in every computer I've used for several years now, but when I checked its memory usage eclipse was using around 250mb. I've asked a friend who uses a netbook with 1gb of ram and he uses eclipse without issue on a regular basis as well, so I'm really not sure where this myth comes from. Maybe people are just loading up their eclipses with a ton of plugins?
